and useful Improvementsin Wild-Oats Separators, of which't he following is a" specification. V Our nvention relates.to'separators and I more particularly to a wild oats separator for separating wild oats from wheat, barley, rye, oats andother grain which has no beard appended to the. kernels.

"The primarypbject of our invention residesin the provision of a rotatably mounted and angularly disposed shaft, having novel means mounted thereon in the form of-a cylindenthe latter being peculiarly formed for causing the wild cats to adhere to the interior thereof, the shaft also having mounted thereon ;a grain receiving means, the latter having associated therewith a cleaning means which coacts with the interior of the cylinder for cleaning the wild oats therefrom I Another object of our invention resides in the provision of a novel means associated with the supporting means for the-shaft for receiving grain and transmitting the same into the interior of the cylinder, the latter having novel means associated therewith for facilitating the exitof theclean grain.

A further object of our invention resides in the provision ofa novel means associated with the wild oats receiving means within the cylinder for receiving the Wild oats therefrom and transmitting the same'into a suitable receptacle.

A still further object of our invention resides in the provision of a novel means for detachably securing.the-cloth, to which the grain adheres, to the wheels, the latter with the cloth forming the cylinder.

A still furtherioblject ofour invention resides in the provision ofia novelmeans "associated w1th..the, w1ld,oats receivingmeans .fOILnl itlIitftlIlll'lg. thesame, at all times, in asubstantially vertical-plane...

- A- still further object of our inventioniresides in the provision ofa novel means for Iadjustably mounting the. supporting means -.for varying the disposition of the angle of the shaft.

A still further objectof our invention resides "in the provision of a device of the characterldescribed that is simple in construction, eflicient in operation and one that can be manufactured and placed on the market at a minimum cost.

Other objects as well as the nature, chara oter istic features and scope of our invention will be more readily understood from the following description taken in connection with the accompanying drawings and pointed out in the claims forming a partof this invention.

In the drawings :Figure l is a side-elevational view of our invention; Fig. 2 is a longitudinal sectional view of our invenis an end elevational view of our invention showing especially the hopper mounted on the support and the means for varying theheight of the frame; Fig.

is a 'sideelevational view of the cylinder showingv especially the construction of the Wild oats receiving means and means associated therewith for holding the same in a vertical position.

Referring more particularly to the drawings in which similar reference numerals designate 'like or corresponding parts throughout the different views, we provide a support which :in this instance consists essentially of a substantially rectangular frame including side pieces 1 and end pieces 2 formed of. any desired material, preferably Wood, one of the end pieces having-angle irons 3 having portions thereof secured to the ground floorand the upstanding portions being provided with slots inwhich are slidably mounted bolts 4, the latter being engaged on their outer end by means of nuts )5 for frictional engagement with the upstanding portions of the irons 3 for holding the end of the frame at various angles to the ground. The end pieces 2 have vertical standards 6 and 7 rigidly secured thereto at points approximately intermediate their ends, thejfront standard 6 being slightly ,longer than the rear standard and which standards are provided adjacent their upper endswith inclined openings about which openings are rigidly secured on-the respective sides of the standards by means of nut andbolti arrangements 8, shaft collars 9, the ,latter with'the openings forming suitable bearings for the shaft 10 rotatably mounted rigidly connected to the outer ends thereof clearly. shown in the drawings.

therein and disposed at a slight angle to the ground becauseof the arrangement of the arms 6 and 7 and the openings therein as In order to rotate the shaft, we have provided the forward end. thereof which extends slightly beyond the standard 6 with a crank handle ll.

Rigidly mounted on the shaft 10 intermediate the shaft collars 9 is our improved grain receiving cylinder generally designated 12 and which in this instance consists essentially of forward and rear wheels 13 and 14 and a cloth 15, the forward wheel 13 is suitably supported from the shaft by means of a hub 16 rigidly connected to the shaft by means of a pin 17 the hub having radiating therefrom spokes 18 which have the wheel rim 19, the outer end of which is bent slightly arcuately and inwardly from the outer periphery and has a circumferentially extending rib 20 formed integral therewith adjacent the inner edge for a purpose to be hereinafter described. The rear wheel lt is supported from the shaft by means of a hub 21, the latter having spokes 22 radiating therefrom which extend through and support an inner curved rim 28, to be hereinafter described, the free ends of the spokes having rigidly connected thereto the outer rim 2a, the outer periphery of which is provided with a circumferentially extending rib 25, the latter receiving one end of the cloth 15, which is formed preferably of fleecy material to facilitate the adhering of the wild oats thereto. The cloth is secured to the rear wheel 14: about the rib 25 by means of suitable clamping rings 26 disposed on the respective sides of the rim, the cloth being extended and suitably flexed and secured to the forward wheel 13 about the rib 20 thereon by means of suitable clamping rings 27 similar in construction to the rings 26. By the provision of the cloth, which is preferably fleecy, a flexible cylinder is provided for cooperation with the scraping means to be hereinafter described. The clamping rings permit of the removal of the cloth when the latter has become worn, whereupon the cloth can be reversed and again adjustably clamped on the wheels so that the desired flexibility can be procured.

Loosely mounted on the shaft 10 and disposed within the cylinder 12 by means of supporting bars 28 which are sleeved to the shaft intermediate their ends, is the wild oats grain receiving means, the latter being rigidly connected at its upper end to the upper ends of the bars. In order to hold the bars 28 in position to prevent the sliding movement of the same on the shaft, we have slidably disposed collars 29 thereabout, which collars are held in rigid position against the arins, the latter bearing against the hubs of the wheels 13 and 14, by means of the pins 30.

In order to hold the grain receiving means in a substantially vertical position, wehave in this instance provided weights 31 and rigidly connected the same to the lower ends agonally to the lower .end of therear wall 7 and with the rear wall constitutes .a chute 35, the outer end of which extends to one side'of the rear supporting bar 28 and is positioned above the rim 23 carried by the wheel 14. A bearing 36 is secured to the slanting bottom 34 and is disposed about the shaft at a point substantially intermediate its ends for suitably supporting the hopper thereon, the shaft also extending through an opening 37. in the rear wall as clearly shown in the drawings. The sides of the hopper taper toward the chute 35 as clearly shown in Fig. 4L of the drawings and facilitate working of the grain therethrough. 7

Suitable scraping means have been provided for removing the wild oats which has adhered to the inner surface of the fleecy cloth 15 as the same is being rotated and in this instance consists essentially of a bar 38,

the latter extending longitudinally for the entire length of the cloth and arranged in close relation with the cloth and is adjustably supported on the supporting bars 28 by means of depending slotted arms 89, the latter being adjustably mounted about suitable nut and bolt arrangements 40 on the f upper ends of the arms.

For the purpose of inserting mixed grain into the cylinder 12 preparatory to the separation of the wild oats from the grain, we

have provided a hopper 41 and rigidly mounted the same on the upper'end of the forward arm 7 by means of a bracket 42 and fastening device 48, the lower end of the hopper terminating in a spout 44, which spout is positioned slightly above the rim 19 of the forward wheel 13 as clearly shown in Fig. 2, the curved rim serving to guide the grain into the slantingly disposed cylinder 12. In order tore cei've the wild oats after the same has passed from the hopper 32 and upon the ring 23, we have rigidly mounted to the inner face of the rear standard 7 by means of a bracket 45 and-suitable fastening devices 46. the rear wall ofa hopper 4:7 the front wall of which conforming substantially to the outer periphery of the ring 23 and being arranged in close relation there-with, the hopper having a chute 18 extending therefrom for facilitating the guiding of the wild oats into a suitable receptacle, not shown.

Suitable means have also been provided for receiving the clean grain from the lower end of the cylinder 12 and in this instance consists essentially of an arcuate hopper 49 which conforms substantially to the outer periphery of the lower portion of the cylinder and is substantially U-shaped in cross section, the outer wall of which is extended slightly above the inner wall and conforms substantially tothe configuration of the under surface of the hopper -17 positioned slightly above the same and which hopper 19 has a chute 50 projecting downwardly therefrom at aslight inclination from a point substantially intermediate the ends, the hopper being supported in this position by means of a bracket 51, the latter being secured to the inner face of the rear standardadjacent the lower end thereof by means of a suitable fastening device 52 and has the extreme free end thereof bent into a sub stantially U-shaped form to conform to the configuration of the lower portion of the hopper l9 and is arranged in close relation therewith for supporting the hopper.

The operation of our invention is as follows: When it is desired to separate wild oats from the grain, for instance wheat, the mixed grain is inserted in the hopper 11 and through the instrumentality of the chute 44 at the lower end thereof, the gran is allowed to pass into the cylinder 12, the curved rim 19 facilitating the entrance of the grain into the cylinder. The shaft 10 is now rotated by means of the crank handle 11, the rotation=of the shaft imparting rotary movement to the cylinder 12 and because of the beard which is on the wild oats, the latter will adhere to the fleecy cloth 15 and be carried upwardly to a point adjacent,

the scraping bar 38' which is arranged in close relation with the inner surface of the cloth whereupon the wild oat kernels will be engaged by the bar 38 and dropped into the wild oats receiving hopper 32 whereupon the same will, due to the slanting bottom 34;, be transmitted through the chute 35 and deposited upon the curved rim 23, which because of its peculiar formation will not retain the grain but cause the same to slide therefrom into the hopper 47 and thence through the chute 48 into a suitable receptacle, not shown. During this operation the wheat kernels or clean grain that has no beard attached thereto will not adhere to the fleecy cloth but will slide along the lower portion of the cloth due to the inclination of the shaft and cylinder and will be deposited in the chute 49 positioned at the rear end of the cylinder, whereupon the grain will thence be transmitted through the chute 50 and deposited in a suitable receptacle, not shown. If it is desired to adjust the inclination of the shaft 10 and cylinder 12 which has its outer edges arranged in parallelism with the shaft, all that is necessary to do is to loosen the nut 5 upon the bolt 1 positioned on the forward end of the frame and adjust the same by means of the bolt and slot in the upstanding portion in the angle iron until the required distance is obtained, whereupon the nut -1- is then tightened and securely holds the same in position. Should it be desired to vary the tension of the cloth 15, all that is required is to loosen the clamping rings 26 or 27 and place the cloth in the desired manner and then replace the rings.

Although we have shown and described the preferred embodiment of our invention, we desire to be understood that we are not limited to the exact details shown, however, great stress is laid upon the arrangement of the shaft disposed at an angle to the ground floor and having the cylinder rigidly mounted thereon and the peculiar mounting and arrai'igement of the grain receiving hopper 32 and the scraping bar 34: cooperating with the interior of the cloth for the purposes set forth.

From the above description taken in connection with the accompanying drawings, it can easily be seen that we have provided adevice that is simple in construction, containing but a few simple parts that can be cheaply manufactured and assembled and when assembled can be placed upon the market and sold at a minimum cost.

It will be understood that the above de scription and accompanying drawings comprehend only the general and preferred embodiment of our invention and that various minor changes in detail of construction, proportion and arrangement of the parts may be made within the scope of the appended claims and without sacrificing any of the advantages of our invention.
